Yes you can return it, and yes Ikea will exchange a piece of a product so you don't have to disassemble the item
Ikea is awesome with returns as long as you have the receipt.
Per the IKEA return policy - Something is wrong with my product, what should I do? We’re really sorry that you have an issue with your product. Depending on the issue, there are several options available: DAMAGED/FAULTY PART – You can take just the part and your receipt to an IKEA store and we will exchange this for you. Alternatively, you can return the entire item for an exchange or a refund. If you can’t make it back to an IKEA store, you can contact us and we will discuss options with you
